What undesirable effect can occur when using a noise blanker?
Received audio in the speech range might have an echo effect
The audio frequency bandwidth of the received signal might be compressed
Strong signals may be distorted and appear to cause spurious emissions✓پاسخ درست
FM signals can no longer be demodulated
توضیح
The blanker gates the receiver off whenever its wideband detector sees a large amplitude excursion, and a strong signal within that detection bandwidth can trigger the gating. Chopping the desired signal this way creates sidebands that appear across the passband as spurious signals.
